Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread patternis repeated throughout the circumference of the tire, the opposite side being substantially the same as that illustrated; and,

FIG. 2 is an enlarged fragmentary plan view of the tread pattern of FIG. 1 showing my new design.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
